Sensibilidad y especificidad de las pruebas diagnosticas de la tuberculosis

Abstract

The tuberculosis is a problem of Public world Health with a rate mortality of 1.7 millions, of which 0.4 million of infected were diagnosed of HIV. In Ecuador 5.134 new cases of tuberculosis were brought in the year 2016 being the provinces of the Guayas and The Gold those who bring a significant increase of 2863 and 294 cases respectively. (1) Nowadays the clinical, radiological and microbiological criteria allow the diagnosis of the disease. I target: Determine the sensibility and specificity of the diagnostic tests of the tuberculosis Methods: it is a question of a descriptive study based on the review of scientific articles in databases of PubMed, Elsevier, Sciencie direct, limiting the search to articles in magazine indexed of last 5 years, in Spanish and English; besides guides and in force regulations in the Department of Public Health. Conclusion: The diagnostic tools based on molecular studies, 92.4 % and 97.1 % have a sensibility and specificity but due to his high cost they are little used in the endemic countries of tuberculosis. The baciloscopia in Ecuador constitutes the method of early diagnosis with a sensibility from 22 to 80 % and with a specificity of 90 %. (2)
